Ingredients

Directions

Make the soup

  1. Melt the butter in a saucepan and stir in the flour until smooth.

  2. Gradually add the milk and enough of the asparagus cooking water to achieve a creamy consistency.

  3. Stir in the asparagus pulp and bring to a boil.

  4. Season with salt, white pepper, and nutmeg, then remove from heat.

Finish and serve

  1. Beat the egg yolk with a little soup.

  2. Stir the beaten yolk into the soup.

  3. Serve immediately, ensuring the soup does not boil after adding the egg.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Enriches the base and carries flavor while forming the start of the roux.
Flour
Thickens the milk mixture into a smooth, creamy body.
Milk
Forms the creamy liquid base of the soup.
Asparagus pulp
Provides the main asparagus flavor and body to the soup.
Egg yolk
Enriches and thickens the finished soup for a richer texture.

The step that matters

Do not let the soup boil after adding the egg yolk. Egg yolk proteins set and curdle when overheated, which would make the soup grainy. Tempering the yolk with hot soup first helps prevent scrambling.

Swap the white pepper

How well each one fits the dish's main ingredients (butter, flour, milk, asparagus, nutmeg, egg):

  1. Cinnamonfits better
  2. Tarragonfits better
  3. Capersfits better
  4. White pepperthe original

Fit is the average pairing score against butter, flour, milk, asparagus, nutmeg, egg. Candidates are from the same food group and used in at least 100 recipes.
